Fig. 5　High resolution DTI.(A, B) The reduced FOV SNR was improved by the reduced FOV method.(C) With multi-band SENSE and increasing the number of MPGs axes to 128, a clearer tract of the lumbar nerves was obtained. In the spinal canal, SNR values were 4.87±3.70 for rFOV and 1.84±0.78 for cFOV, showing a significantly high SNR with rFOV compared with cFOV. In MPG128 axis, the lumbar nerve is clearly drawn to the distal side compared with 15 axis(arrow) . From Eguchi et al., modified with permission［17］
